Subject: bug#19973: Grafts break debug outputs
Date: Sun, 01 Mar 2015 00:06:11 -0500 [thread overview]
Message-ID: <878ufh71do.fsf@netris.org> (raw)
Grafts break debug outputs, or at least that's my guess.
Here's what I see:
mhw@jojen:~$ guix build guile
guix build: warning: ambiguous package specification `guile'
guix build: warning: choosing guile-2.0.11 from gnu/packages/guile.scm:110:2
/gnu/store/3lhr8q28q6f59774di9av7ncy09jd55d-guile-2.0.11
/gnu/store/rgv3fvy6xqp6966rfh8v6fv7m48abcbh-guile-2.0.11-debug
mhw@jojen:~$ guix package -I guile

mhw@jojen:~$ ls -l .guix-profile/lib/debug/gnu/store/

I guess GDB can't find the debugging information because
122jv790mv2mlnylbrbzav65vghbw93n-guile-2.0.11 is the name of the guile
directory *before* grafting.
To work around this, I created my own ~/mydebug directory:
mhw@jojen:~/mydebug/gnu/store$ ln -s /gnu/store/rgv3fvy6xqp6966rfh8v6fv7m48abcbh-guile-2.0.11-debug/lib/debug/gnu/store/122jv790mv2mlnylbrbzav65vghbw93n-guile-2.0.11 3lhr8q28q6f59774di9av7ncy09jd55d-guile-2.0.11
and then pointed GDB at ~/mydebug and then debugging works again.
